title: Robotic rectal surgery: what are the benefits?
abstract: Robotic rectal surgery is not a rare event for colorectal surgeons any more. Even patients with colorectal diseases obtain information through the mass media and are asking surgeons about robotic surgery. Since laparoscopic rectal surgery has proved to have some benefits compared to open rectal surgery, many surgeons became interested in robotic rectal surgery. Some of them have reported the advantages and disadvantages of robotic rectal surgery over the last decade. This review will report on the outcomes of robotic rectal surgery. Robotic rectal surgery requires a longer operation time than laparoscopic or open surgery, but many authors reduced the gap as they were accustomed to the robotic system and used various additional techniques. The high cost for purchasing and maintaining the robotic system is still a problem, though. However, except for this reason, robotic rectal surgery shows comparable and even superior results in some parameters than laparoscopic or open surgery. They include pathologic and functional outcomes as well as short-term outcomes such as complication rates, length of hospital stay, time to recover normal bowel function or first flatus, time to start diet, and postoperative pain. Moreover, studies on oncologic outcomes show acceptable results. Robotic rectal surgery is safe and feasible and has a number of benefits. Therefore, it can be an alternative option to conventional laparoscopic and open surgery with strict indications.
